SPECIFICATION forming para of Letters Patent No. 506,713, dated october17,1893.

Applicatie; ned my 23, 189s'. sean No. 475,246. (No moda.)

13e it knownA that'I, ALBERT H. MoRToN, acitlz'en of the United States,residing at Lowwealth of Massachusetts, have invented a cer'- chines forFeeding Textile Fibers, of whic the following is aspecifcation. A Myinvention relates to machines for feeding tejitle fibers of that classin which spiked or toothed lifting-aprons are employed to raise suchfibers from-a hopper or supply box ing surface of the machine to besupplied, and the obJect of said invention is so to regufurnishedthereby will be substantially uniform at all times.

In the accompanying drawings, Figure 1 is a slde elevation of a feedingmachine, showingthe feed-apron and its rolls, the liftingapron and itsrolls, the doer, the rotary comb and-1ts clearing devices in-dotteddines (a small part of the lifting-apron and comb be-v ing shownin full lines, a part of the frame of the machine being broken away 'forthat able speed-mechanism for driving the liftingapron and a part of thesystem of levers which control said speed-mechanism, showlng thefeed-rolls and feed-apron of said lastdotted lines; Eig.v 2, a frontelevation of a part of the frame of a cottonopener or similar machine,the feed-rolls and a system of scale-levers such as may be used tocontrol the mechanism which drives the lifting-apron. I

A represents the frame ofl the feeding-machine, the space a, inclosed bythe sides of the machine, the end-piecev a', the lifting-apron B and thebottom or feed-apron C forming a hopper or supply-box, in which thestock is placed. The stock is carried toward the lifting-apron B by afeed-apron C, said aprons T C being endless belts, the apron 13 runningn the parallel rolls b b and the apron C on the parallel, rolls c c',said apron B having transverse slats bprovided with teeth b3,in-

clined in the direction in which said apron B travels,and said apron C'being driven from the apron B by gears b? c2 fast on the respectiveshafts of the apron-'rolls b c and engaging the intermediate gear c3. Dis a rotary comb which removes surplus stock from the lifting-apron, thespikes ofl said comb being stripped by a perforated belt d, running lonsaid comb and on an idle-roll d', as fully described in Letters Patentto me,-No.'475,24=6, dated May '17, 1892. E represents ,the doer whichremoves the stock from 4the liftingapron. All of the above mentionedparts arerv ot'ia Well known construct-ion and operation, except ashereinafter stated. l

It is customary to run thelifti-ng-apron and feed-apron at a uniformrate of speed, as by a belt connecting pulleys on the shaft of the upperlifting-apron roll and on the pulley f4 hereinafter named.'

i G indicates* ak picker, opener orother mato which fibers may besupplied by the lifting-apron B, said feed-apron g conducting the fibersto feedv chine, having a feed-apron g rolls gi g2, and to anotherfeed-roll or sectional evener-roll G arranged above the rolls asis'shown .in the patent to Clarke and Perham, No. 245,609, dated August16,1881. 'lhe sectional evener-roll G may represent any sectional;feed-surface between which and a feed-roller or feed-rolls the fibersare fed, as

the sectional evener-plates'or feed plaies shown in the patentto\Vhitehead,No.110,318,

dated December 20, 1870, provided the sections of such sectional feedsurf ace independently yield according to thc thickness of stock passingbetween said sections andthe feedroll or may represent any yieldingfeed-roll'J or feed-plate. Such a vyielding combined with leversoperated thereby constitutes an evener and is commonly used to controlthrough intermediate mechanism, the speed of feed-rolls, according tothe amount of stock passing between said feed-rolls and said yieldingfeed-surfaces. l

H represents a system of scale-levers in three series, the scale-leversh each resting upon two sections of the roll G', the -levers h of thesecond series each resting upon two levers h of the first series and themain scalelever h2 resting upon two levers h'iof the secfeed-device IOO,2S iowsaid'beln f5,

This variable speed mechanism consists ofreversed speedcones F F', one, F, .of which is driven by bevel-gearsff', one, f, of which gears islfast on the shaft of said cone F andengages theother bevel-gear f', the latter being secured to aband-pulley f2, concentrieally therewithY and said band-pulleybeingconnected by.a-band f 3 to another band-pulley f4, driven-at auniform speed from the ma,- chinelto which fibers are fed. The cones are.conne has's 'cured toits shaft abevel pinienj"6 which engages abevel-gearb1 on theshaft of the stantially as shown in 4said ham patent,havingsegmental gears f9 1.

f Itis evident that when the sectional evenerro'llG orany part thereofis raised, the slotted end of the lever f2 will also beraised, its otherend depressed and the belt f5` moved towardthe large en d ofthe drivencone Fand the small end of the driving cone F, thus diand .that'when thethickness of stock'between saidsectional evener-roll and the feed-rolls'1 g g2 ,is diminished, the sectional evener-roll -will approach saidfeed-rolls and the weight will by the means above deted b ya belt f5andthe driven cone F Clarke and /Per whicllextend above and be-v secr/1escribed raise'lhe belt on the cones F F and cause stock to be fedthereby more rapidly on to the feed-aprong. By the means above describedof varying the speed of the` lifting-apron, the apron g of \the machineG will be furnished with a substantially uniform `supply of fbers.-
